| * | Introduce block dma helpers (Avi Kivity) | aliguori | 2009-02-05 | 1 | -0/+8 |
| | | | | | | | | | | | | | These helpers perform read/write requests on entire scatter/gather lists, relieving the device emulation code from mapping and unmapping physical memory, and from looping when map resources are exhausted.

| * | Add a scatter-gather list type and accessors (Avi Kivity) | aliguori | 2009-02-05 | 1 | -0/+33 |
| Scatter-gather lists are used extensively in dma-capable devices; a single data structure allows more code reuse later on.
